Global Warming, Greenhouse Gas Emissions | featured news

Despite 20 years of effort, greenhouse gas emissions are going up instead of down, hitting record highs as climate negotiators gather to debate a new global warming accord.

The world's top greenhouse polluter hosts week-long U.N. climate talks from Monday aimed at sealing a broader pact to fight global warming and helping poorer nations with money and clean-energy technology.

Saying that that richer countries were not doing enough to cut emissions, developing countries’ delegates upended climate talks on Monday.

Four of President Barack Obama's top environmental and energy officials are urging the Senate to pass legislation to reduce emissions of the gases linked to global warming.

The heads of the Energy Department, Agriculture Department, Interior Department and Environmental Protection Agency told a Senate panel Tuesday they should pass a bill similar to one the House narrowly cleared late last month. That legislation would impose the first limits on greenhouse gases, reducing them by 80 percent by mid-century.
